nice, do you have to pump the oil exchange or is some sort of siphon or gravity heat rise system? what is the third hole for temp sensor or vent?

- uses a pump
- diff vent, it's in the non-intercooled as well.

new springs.... shorter

so in news.edited Comp Cams card is for HOT lash... not cold lash... they must be trying to save ink....edited

alright, think I'm ready for dyno tuning on Friday.

[SuperBuickGuy]

and yes, I spent a lot of money solving a problem I didn't have..... ah well, the trolls get a laugh.

your car looks like a panther coming out of the jungle ready to leap on a predator....i love it

Most of us are just trying to improve our skills and learn from others. Too bad that there are critics out there discouraging people from sharing.

Looking good. Keep up the good work.

[bobs77vet]

screw the critics....I like what you are doing and its your car and your dime, so do what ever the eff you want.

what about the gas tank vent clamp? did that fix the leak?

[SuperBuickGuy]

the clamp fixed it

as for the trolls... I didn't know that Comp Cams defaulted to Hot with the solid roller cam. I could 'save face' and simply not say anything - but my purpose of blogging is to encourage others to share in my passion - even when I make a mistake (though I still wonder why Comp Cams didn't feel the need to add that one word - sure, it's obvious afterwards) build your car, it's not going to be perfect, even after you have lots of years of experience doing it. TV alleges that a car will run perfect after a week-long build. It doesn't, but it's okay, this is real world. stuff is going to happen, there's nothing to be ashamed of, and trolls are going to do what they do anyway... let them laugh, I have a sweet C3 they have their mommy's basement and an iPhone 4.

shorter front springs

there, balanced

old list

new list this is for max points in engineering... I may even cave and put some kind of radio in it...edited

since it was on the list, the ramps

376 to the tire

for the record... we didn't mess with the timing.edited It has 18* initial then I think 20 mechanical... at this point it's not knocking and the motor is still 'new' .... safe tune get some more miles under it and maybe I'll revisit the timing.... I have my eye on the coil per cylinder conversion.....edited

thats pretty awesome especially if you havent dialed in the timing. i am sure there is some hidden power in optimizing the timing.

guess is at least 25 hp more. Since this 40% more then what I ran 2x before... thinking I need to get used to that.... and yet

humph.edited I went to PIR, they have noise limits.... 97 db noise limits. if you've been following along, you'll know that my noise at full song is 111 db.edited I didn't find out before I went but I'm so glad I did because I spent time with my parents - something that's been hard to do since I saw them a year ago....edited

but I have a problem to fix.edited Thinking a corkscrew with some steel wool as the first shot.edited I'm also not against injecting water to muffle the sound... I really need to be below 105 - from there it's arguable....edited

"Sounds Like" you need reverse Cut-Outs. So, cut outs are to open the system and get the HP - but yo have the opposite challenge. I did a quick dive. [seemed like a clever idea and wondered if anybody had done it before.]

Check out this video:

At about 2:10 he gets to the meat of the mod.

More weight, some complications, and if you went electric - could forget to switch and be Black Flagged - but an approach to consider. Any number of options in the aft (muffled) section to get to 97dB (or less). NOTE: when in OPEN - there is still flow through the aft section - you'll see that in the video when he fires it up.

Cheers - Jim

I don't know where in "class" your car fits - but the aft exhaust could blow a diffuser for some DF.

The HP numbers* suggest I should change the entire system. The biggest issue with a cut out would be the individual runners don't meet a collector before they're outside the car. I'm pretty sure I don't have the time to fabricate an exhaust before the end of May; however, next winter I may fully refab this to put regular headers that go into side pipes ... for now, what you suggest may be the only solution... I'm also thinking a perforated corkscrew baffle with steel wool to absorb sound near the tip.

*the HP numbers, hopefully I'll get the sheets today, drops off at 6500 - otherwise it was well on its way to a lot more at the wheel. The motor basically starts making great power at 3500 then climbs a wall to 6500 where something else is happening.... need to analyze (valve control, spark control, fueling....)

​so let's try this
